CROSS REFERENCE TO RELATED APPLICATIONS

The present Application for Patent claims priority to ProvisionalApplication No. 63/085,930 entitled “CANNABIS PLANT NAMED ‘RedKROSS02-BK’” filed Sep. 30, 2020, which is hereby expressly incorporatedby reference herein.

Latin name of the genus and species: Genus—Cannabis. Species—hybrid.

Variety denomination: The new Cannabis plant claimed is of the varietydenominated ‘Red KROSS02-BK’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct annual variety of aCannabis hybrid, which has been given the variety denomination of ‘RedKROSS02-BK’. ‘Red KROSS02-BK’ is intended for use in industrialapplications, for example, as a source of fiber, pulp, biomass, seed,and seed oils that serve as raw material for textiles, paper products,construction materials, animal forage, dietary supplements and/orcannabinoid extracts, distillates, and isolates.

SUMMARY OF THE INVENTION

The new variety was developed from plants initially produced from theopen pollination of the hybrid variety ‘Ringo's Gift’ (not patented) bya hemp hybrid variety known as ‘Red Kross’ (not patented) that is the F1offspring of the hemp hybrid varieties ‘Baox’ (not patented) and‘Finola’ (not patented). After pollination, F1 seed was collected andsubsequently planted on a 20-acre plot.

Successive, multiple family group selection was carried out in order todecrease harvest time to 80-100 days, increase stem productivity andfiber content, and decrease the content of tetrahydrocannabinol (THC)compounds while keeping cannabidiol (CBD) levels above 10%. Selection byanatomic structure of cross section of the stem and high terpeneprofiles in the flowering stage was also included.

100 self-pollinated F2 plants were selected based on vigor and desirablephenotypic characteristics. This initial selection was followed by asecond selection of 5 plants from among the 100 plants initiallyselected. The 5 plants were allowed to self-pollinate, and F2 seed wascollected and then grown on a 1-acre plot. Cannabinoid profiles of F2plants were tested, and the new variety was selected as a single plant.

A phytochemical profile characterized by ultralow or undetectable levelsof all cannabinoid compounds except for cannabidioloc acid (CBD-A),specifically undetectable levels of the cannabinoid compounds:cannabigerolic acid (CBG-A), cannabigerol (CBG), CBD,Δ9-tetrahydrocannabinolic acid (THC-A), Δ9-tetrahydrocannabinol(Δ9-THC), Δ8-tetrahydrocannabinoil (Δ8-THC), Δ10-tetrahydrocannabinol(Δ010-THC), cannabichromenic acid (CBC-A), cannabichromene (CBC),cannabigerovarinic (CBGV-A), cannabidivarinic acid (CBDV-A),cannabidivarin (CBDV), tetrahydrocanabivarinic acid (THCV-A),tetrahydrocannabivarin (THCV), cannabichromevarinic acid (CBCV-A),cannabinol (CBN), cannabicyclol (CBL), and cannabinodiolic acid(CBND-A); cannabidiolic acid (CBD-A) levels under 10% w/w; and totalcannabinoid levels under 10% w/w.

Multiple clones of the selected plant were created. The followingcharacteristics of the new variety have been repeatedly observed in eachof the clones and can be used to distinguish ‘Red KROSS02-BK’ as a newand distinct variety of Cannabis:

1. A phytocannabinoid profile characterized by

-   -   a. Undetectable levels of the cannabinoid compounds        cannabigerolic acid (CBG-A), cannabigerol (CBG), CBD,        Δ9-tetrahydrocannabinolic acid (THC-A), Δ9-tetrahydrocannabinol        (Δ9-THC), Δ8-tetrahydrocannabinoil (Δ8-THC),        Δ10-tetrahydrocannabinol (Δ10-THC), cannabichromenic acid        (CBC-A), cannabichromene (CBC), cannabigerovarinic (CBGV-A),        cannabidivarinic acid (CBDV-A), cannabidivarin (CBDV),        tetrahydrocanabivarinic acid (THCV-A), tetrahydrocannabivarin        (THCV), cannabichromevarinic acid (CBCV-A), cannabinol (CBN),        cannabicyclol (CBL), and cannabinodiolic acid (CBND-A);    -   b. cannabidiolic acid (CBD-A) levels under 10% w/w;    -   c. total cannabinoid levels under 10% w/w; and        2. an autoflowering vs. photoperiod reproductive cycle.

Plants of the new variety differ from plants of the seed parent ‘Ringo'sGift’ and from the pollen parent ‘Red Kross’ in their phytochemicalcontent. In particular, ‘Red Kross02-BK’ differs from both parentstrains in that it has ultralow or non-detectable levels of allcannabinoid compounds except for cannabidiolic acid (CBD-A),cannabidiolic acid (CBD-A) levels under 10% w/w, and total cannabinoidlevels under 10% w/w. These differences make the new variety especiallydesirable for industrial uses because a phytocannabinoid profile thatlacks psychoactive cannabinoidsexempts the plant material and oilextracts from prohibitions imposed by the Controlled Substances Act andgreatly reduces or eliminates the need to remediate extracts to removepsychoactive cannabinoids. Production costs and efficiency are therebygreatly improved, making the variety especially useful and desirable forindustrial applications such as preparing CBD-A isolate.
